CABLE-RA I LWAY APPLIANCE.

SPECIFICATION forming part of Letters Patent No. 296,602, dated April 8, 1884. Application filed August 31, 1883; [No model.)

To aZZ whom it may concern.-

Be it known that LWILLIAM HENRY PAINE, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cable Railways and Appliances Therefor, of which the following is a specification.

The subject of my invention is a device to maintain the requisite tension in the ropes of a cable railway, and to take up the slack occurring from reduced tension at any point, resulting from variations in the draft or tension on the ropein different positions of the car or train. To this endI employa balance-car carrying an equalizing-sheave, around which the rope is passed, and running on an inclined track, so that the gravity of the car and its accessories will serve to take up the slack in the rope as required. In order to provide for further resistance to the strain upon the rope in one direction, I employ automatic brakes so mounted that they resist the movement of the balance-car up its track, while permitting it to move freely downward as far as the attached rope will allow, so as to take up the slack.

The device can be used at either or both ends of the route, just behind where the cars are started.

In the accompanying drawings, Figure l is a plan of a rope-driving apparatus with my invention applied. Fig. 2 is a side elevation of the same. Fig. 3 is an elevation illustrating amodification.

1 may represent the outgoing rope of an endless cablerailway system passing over stationary guidingsheaves 2 from the drivingdrum 3. The rope 1 passes around the sheave 4, the shaft of which has its bearings in the the rope passes over the stationary guidingsheave 8 to the line.

the frame 5, and resting on the peripheries of the carryingwheels 6 6, so as to resist the movement of the balance car uphill, while permitting it to move freely downhill by its own gravity. The efi'ect of this arrangement is that the balancecar, being on the outgoing rope, takes up the slack caused by attaching the car or train of cars to this rope. The stress caused by the attachment of the car or 5 train with the stress caused by the gravitating balaneecar, while descending, makes up the sum of the stresses on the rope at this point. After the car or train is in motion or has departed, the rope is only subjected to the stress 6 of the balance-car, which, by the action of the brakes, maintains the same tension and prevents the sagging that would otherwise occur in the rope behind every departing car or train, thus maintaining greater uniformity in 6 the stress and preventing loosening or undula tions in the rope.

In Fig. 3 I have shown a modification in the construction of the gravitating balance-car, the equalizing-sheave 4 being placed in a hori- 7 zontal position instead of vertically,as in Figs.

1 and 2.

Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent: 7

1. The combination, with a cable railway, of a gravitating balance-car provided with an automatic braking device, as and for the purpose set forth.

2. The combination, with a cable railway,

' of the balancecar 4 5 6, and automatic brakes WILLIAM H. PAINE.
